Exception Handling

• An error that arises through mistakes in coding or through incorrect data entered by the user is called an “exception”
• Such errors that are encountered while a program runs are said to be “thrown”
• Programmers try to anticipate these errors and either prevent or solve them before they happen
• Java uses the “Try... Catch...” process in order to try running a block of code to test for errors and then catch an error if it occurs
• All “Try” statements must be followed by at least one “Catch” statement or a “Finally” statement
• Exceptions that occur that are not handled by a “Catch” block of code or a “Finally” block will cause a program to terminate
